mybatis返回key value map集合

XML:文件 

    SELECT id,name FROM user        



    
    

Service实现类： namespaceXml根据自己xml命名取

import org.apache.ibatis.session.SqlSession;
@Autowired
private SqlSession sqlSession;

public Map getBasicInformationOfCompanyPersonnel(String status) throws Exception {
Map params = new HashMap<>();

    params.put("status", status);

    MapResultHandler handler = new MapResultHandler();

    Map result = handler.getMappedResults();

    sqlSession.select("namespaceXml.getData",params,handler);

    return result;
}

工具类： 

import org.apache.ibatis.session.ResultContext;
import org.apache.ibatis.session.ResultHandler;

public class MapResultHandler implements ResultHandler {

    @SuppressWarnings("rawtypes")
    private final Map mappedResults = new HashMap();

    @SuppressWarnings("unchecked")
    @Override
    public void handleResult(ResultContext context) {
        @SuppressWarnings("rawtypes")
        Map map = (Map) context.getResultObject();
        // xml配置里面的property的值，对应的列
        mappedResults.put(map.get("key"), map.get("value"));
    }

    @SuppressWarnings("rawtypes")
    public Map getMappedResults() {
        return mappedResults;
    }
}
